Study of the Vaginal Microbiota and the Potential of a Vaginal Probiotic Cream in Vaginal Candidosis

June 3, 2019 updated by: Ethisch Comité, UZA, University Hospital, Antwerp

Studie Van de Vaginale Microbiota en Het Potentieel Van Een Vaginale Zalf Met Probiotica Bij Vaginale Candidose

This study evaluated the effect of a vaginal gel containing three live probiotic bacteria on vaginal Candida albicans infection in flemish patients (n=20). The therapeutic effects of the gel will be clinically evaluated (vaginal pH, microscopic and clinical scores). The effect on the vaginal microbiome will be evaluated through 16S ribosomal RNA amplicon sequencing via MiSeq Illumina and polymerase chain reaction (PCR) for Candida albicans.

Study Overview

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Study Type

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years to 50 years (Adult)

Accepts Healthy Volunteers

No

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Experimental: vulvovaginitis patients- lactobacillus gel
Daily use of vaginal gel containing lactobacilli by patients. Probiotic vaginal gel.
Other: Probiotic vaginal gel
Total daily administration of 2.5 ml of probiotic gel, containing three lactobacilli (Lactobacillus rhamnosus GG, Lactobacillus pentosus KCA1 and Lactobacillus plantarum WCFS1). Final dosage per gram of gel: 10^9-10^10 colony forming units of lactobacilli.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Vaginal persistence of Candida species
Time Frame: through study completion, estimated 1 year
The presence of Candida species in the collected samples will be analyzed by microscopy, culture (clinical lab) and after DNA extraction through quantitative PCR as molecular method. This will allow to estimate relative and absolute concentrations of the suspected infectious agent, and allow to evaluate if the infection cleared or not.
through study completion, estimated 1 year

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Clinical scores of patients
Time Frame: through study completion, estimated 1 year
By the responsible gynecologist, symptom severity (burning, itching, redness, swelling and fissures) was estimated and scored as absent, mild, moderate or severe. This will provide information about the ability of the gel to ameliorate the symptoms of vulvovaginal candidosis.
through study completion, estimated 1 year
Microbiome analysis
Time Frame: through study completion, estimated 1 year
After Illumina MiSeq sequencing, bio-informatics tools will be used to cluster bacteria and yeasts into operation taxonomic units/ amplicon sequence variants (ASVs). Based on these ASVs, the bacterial and fungal community will be compared over the sampled periods and allow comparison of the composition over the study period. The investigators will specifically screen for ASVs that can be expected to be derived from supplied probiotic strains or that are responsible for the infection (expected Candida ASVs). Additionally, the investigators will pay attention to the dominant members of the vaginal bacterial community (expected in most women to be dominated by one of four Lactobacillus species).
through study completion, estimated 1 year

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
